Answer 1

@Data_LG2 Can you explain this maybe

Answer 2

It looks like all except c are sort of correct... I'm not much help, I'm afraid...

Answer 3

This is the same process like you did before.

#boys in a country team : #girls in a country team = #boys in t&f : # girls in t&f

you have:
\(\sf \large \frac{10\ boys \div 2}{8 \ girls \div 2} = \frac{5 \ boys}{4 \ girls}\)

now which of the following is equal to 5/4 (boys/girls) ?

Answer 4

I mean which of the choices**

Answer 5

5/4 = 1.25

Answer 6

@Data_LG2

Answer 7

So confused :C

Answer 8

the total = 10+8=18
boys = 10/18=55.56
girls = 8/18=44.44

Answer 9

yes, that's right..

which of your choices is equal to 5/4 or 1.25 , if you'll calculate for their ratio?

e.g. choice A: 12 boys and 10 girls = 12/10 = 6/5 which is not equal to 5/4
so this is not the answer.

try doing this with the rest of your choices and tell me which one yields 5/4

Answer 10

c is the answer

Answer 11

15+12=27
boys = 15/27= 55.56

Answer 12
